What day does France go to Church?

Answer 1

In the Catholic Church, not many. France used to be one of the highest countries in church attendance. I think now it is down to only 4% of catholics who attend Mass regularly. In the US, where it used to be 70% in the 1970's, it is down to less than 20%.

Answer 2

For those few Catholics in France who are still practicing their faith, they go to church each Sunday and Holy Day of Obligation.
